Ionic .pi.-conjugated polyelectrolytes by catalyst free polymerization of bis(pyridyl)acetylenes and bis[(pyridyl)ethynyl]benzenes
Original language description
The spontaneous, catalyst free polymerization of four monomers of the bis(pyridyl)acetylene and bis[(pyridyl)ethynyl]benzene types containing either 2-pyridyl or 4-pyridyl groups via activation with benzyl bromide leads to ionic ?-conjugated polyacetylene-type polyelectrolytes (CPEs). All polymers are characterized by means of NMR, IR, UV/vis and photoluminescence spectroscopies, thermogravimetric analysis (TGA) and matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOFMS). The position of the pyridyl groups in the monomer influences the degree of quaternization and the extent of conjugation of CPEs. Monomers with 4-pyridyl groups provide CPEs with a low extent of quaternization [N+/(N+ + N) = 0.27?0.34] and high extent of conjugation. On the other hand, the CPEs derived from 2-pyridyl-containing monomers are highly quaternized [N+/(N+ + N) = 0.77?1.00], however, possess lower conjugation of the main chains. The mechanism assuming quaternization and po
